Discussion: Osmosis is a passive process by which water molecules move through a partially permeable membrane from a region of high concentration to a region of low concentration‚ creating an equal amount of molecules from both regions on each side of the membrane. This process is the result of a downhill energy system known as water potential. Water potential is the potential energy of water (per unit volume) that allows it to move from one area to another by osmosis. This system causes the water

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

For this to happen‚ the molecules need to dissolve through a partially permeable. Osmosis is the diffusion of water as it goes from dilute to a more concentrated solution. Active transport is the movement of molecules from low concentration to high concentration against the concentration gradient. Energy is required for movement to occur

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

The main purpose of this lab is to experiment the molecular polarity on the solubility of solutes in variates of solvents and helped us to determine the polarity of the unknown solute. In this lab‚ we observed the effects of adding polar liquid solutes to non-polar liquid solvents. Materials used: Safety goggles 3 graduated cylinders ethanol‚C2H5OH solid iodine‚ I2 glycerol‚ C3H5(OH)3 water 10 rubber stoppers 10 test tubes kerosene ammonium chloride

Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

The purpose of this lab was to observe osmosis in the Gummy Bears and to investigate the movement of water in and out of a Gummy Bear. The hypothesis stated that the salt will make the gummy bear weigh more‚ but it will keep the gummy bear more intact. However‚ the results showed that the gummy bear decreased in mass because of the salt and water. This contradicts the hypothesis because of how it was believed that the gummy bear would increase in weight‚ but it did the exact opposite. One part of

The main purpose of this lab was to prove the laws of Ohm and Kirchhoff. On another note‚ being able to take part in this lab taught my partner and I the fundamental skills of constructing series and parallel circuit and using a multimeter to calculate the current and voltage of a circuit. I believe that if we only have the
